Broken blend door motor

I replaced the driver side blend door motor due to the sleeve breaking and causing it to over rotate a few times now
Las one lasted 5 months
Is this due to a malfunctioning climate control unit?
Seems that the unit does not sense the stop of the door and keep power to the motor until the sleeve breaks causing the code
I know my circulator doorm

I know my circulator door has same breakage but is impossible to get to
Guess I'm lucky the passenger side doesn't break
Trying to figure out if replacing the motor is a waste or there just that weak

That's how the unit works, it keeps forcing the door against the stop until the resistance in the motor is detected to hit a preset value and it stops sending power. It's hard on equipment doing it that way, but that's what they decided to do rather than limit switches. I repaired mine with a gear type hose clamp. It's a tight fit and you have to line up the screw part in the right orientation or the screw part of the clamp will hit the moldings on the heater bog, but it works and it won't break again. And yep, I'm thankful every day that my passenger side hasn't failed. I'm so paranoid about the crappy setup that I usually don't adjust temp (leave it on high or low), just fan speed.

How did you repair the "sleeve" (or door) the first time it broke? It seems like the repair didn't hold.

Usually, we replace both doors with ones that are much stronger. We don't blame the motor.

It's fairly common for the sleeve on the actuator to split. Mine split on the recirc door and left blend door. Knock on wood I've never had an actual blend door fail, only the actuator drive sleeve/cup things.
